I have a mysql table with a set of x,y points (latitude, and longitude) and I was trying to find some examples on how to implement a inverse distance weighting interpolation formula on those points.  Does anyone know if this has already been done?  I have done a quite bit of searching but have not found any good examples.  Thanks in advance.
